Looking back on my career, even hindsights, tunnel vision, 5 mics

No matter how Eminem looks back at his career, he realizes all he ever wanted was the elusive 5 mic rating in the Source, which he never got, mostly because of his beef with their head guy Benzino. He’s referenced this many times throughout his career.

“And if I ever do live to be a legend
I'mma die a sudden death
5 mics in The Source, I ain't
Holding my fucking breath."
-Say What You Say

Em gets a metaphorical tunnel vision on the times when he beefed with Source for his deserved 5 mics, in the same way Vietnam vets get tunnel visions when remembering the war.
